South Korea New Vehicle Sales August 2026 Fell 28.3%

South Korea Vehicle Sales Decline Sharply in August 2026

South Korea New Vehicle Sales August 2026 declined 28.3% year-over-year to 79,601 units, as weaker domestic and overseas demand combined with strike-related disruptions at Hyundai Motor. All five Korean automakers recorded lower domestic sales than in the same month a year earlier. The decline highlights continued pressure on the country's vehicle market despite differing performance across individual manufacturers and international markets. Kia remained the leading automaker in South Korea, while Hyundai Motor experienced a particularly significant decline. The overall domestic contraction also affected the combined performance of the country's five major automakers, underscoring the impact of softer demand and production disruptions during the month.

Kia Maintains Domestic Market Leadership

Kia led South Korea's domestic market in August with 40,213 vehicles sold, giving the automaker a 50.5% market share despite a 7.6% year-over-year decline. Kia was followed by Hyundai Motor, whose domestic sales fell 41.1% to 34,333 units, representing a 43.1% share. KGM ranked third with 2,300 units, down 43.3% and accounting for 2.9% of the market. Renault Korea recorded 2,024 units, a 47.7% decline and a 2.5% share, while GM Korea sold 731 units, down 39.4%, for a 0.9% share. The results show that every major Korean automaker faced substantial domestic pressure during August.

Overseas Sales Show Diverging Automaker Performance

Overseas sales performance varied significantly among the five automakers. Hyundai Motor's overseas sales, including exports, declined 8.5%, while Kia increased overseas sales by 7.4%. GM Korea recorded a 12.4% increase, whereas KGM declined 5.1% and Renault Korea fell 13.6%. Despite the contrasting results, combined overseas sales decreased 1.2% year-over-year to 508,762 units. The figures indicate that stronger international demand for some manufacturers partly offset domestic weakness, but the overall overseas market was still unable to completely counterbalance the broader decline affecting Korean automakers during August.

Global Sales Fall 6.0% in August

Global sales across the five Korean automakers reached 588,363 units in August, representing a 6.0% year-over-year decline. Hyundai Motor recorded global sales of 288,574 units, down 14.2%, while Kia increased 4.8% to 265,626 units. GM Korea also posted growth, with global sales rising 9.4% to 23,042 units. KGM reported 6,860 units, down 22.6%, and Renault Korea recorded 4,261 units, down 34.0%. The mixed results demonstrate a widening performance gap between manufacturers, with Kia and GM Korea benefiting from stronger sales momentum while Hyundai Motor, KGM and Renault Korea experienced significant declines.

Hyundai Motor Drops Below 300,000 Global Sales

Hyundai Motor recorded a notable milestone in August as its global sales fell below 300,000 units for the first time in four years and seven months. The automaker sold 288,574 vehicles globally, compared with 282,656 units in January 2022, the previous period in which monthly global sales were below the 300,000-unit threshold. Hyundai's August performance was affected by weaker demand and strike-related disruptions, contributing to its 14.2% year-over-year decline. In contrast, Kia extended its positive momentum, recording year-over-year global sales growth for the sixth consecutive month with 265,626 units sold during August.

January-August 2026 Global Sales Remain Mixed

For the January through August 2026 period, global sales trends differed considerably among the five automakers. Hyundai Motor's sales decreased 6.0% year-over-year to 2,575,360 units, while Kia increased 4.3% to 2,191,461 units. GM Korea posted a 12.6% increase to 340,684 units, and KGM recorded a modest 0.6% gain to 72,170 units. Renault Korea experienced the sharpest decline among the five manufacturers during the period, with sales falling 33.0% to 40,675 units. The cumulative figures indicate that Kia and GM Korea maintained stronger year-to-date momentum, while Hyundai Motor and Renault Korea remained under greater pressure.

August Model Sales Led by Sorento

Kia's mid-size SUV Sorento ranked as the best-selling model among the five automakers in August, with 6,397 units sold. Hyundai's mid-size sedan Grandeur followed in second place with 5,931 units, while Hyundai's light-duty truck Porter ranked third with 4,224 units. The model-level results show continued demand for a mix of SUVs, passenger cars and commercial vehicles even as overall domestic sales declined sharply. Sorento's leading position provided an important contribution to Kia's market leadership, while the Grandeur and Porter remained significant contributors to Hyundai Motor's domestic sales performance during a month marked by substantial year-over-year weakness.

Market Outlook After August Sales Decline

The August results point to a challenging environment for South Korea's automotive industry, with domestic sales weakened by softer demand and production disruptions. Although global performance was mixed, the combined decline across the five automakers demonstrates that international gains were insufficient to fully offset domestic weakness. Kia's continued growth and GM Korea's stronger overseas performance provide positive contrasts, while Hyundai Motor's sub-300,000 global monthly result represents a notable setback. The remaining months of 2026 will be important for determining whether demand conditions improve and whether production disruptions ease. Automakers will also need to manage differences between domestic and overseas markets as they seek to stabilize annual sales performance.
